A domestic circuit develops a short circuit. what will be the effect on a fuse wire connected in the circuit?
Answers
Answer:
hey mate I have given answer in explanation also.
If domestic circuit develops a short circuit then the fuse wire connected in the circuit will melt.
Explanation:
When a short circuit develops you get a very large current flowing in the installation circuit. This can damage the wires and could cause a fire etc.. The fuse wire is placed in series with the circuit and is designed to break when the current is greater then the fuse rating. In this way the wiring remains intact but the fuse must be replaced. There are many fuse ratings depending on what would be regarded as maximum for that installation circuit. E.g for lighting installations the fuse value would be low while for heating installations it would be high.
Usually there is a fuse in the socket of the appliance that is being used so that if the appliance is faulty and a short circuit develops then the fuse protecting the appliance breaks. Thus the fuses in the main installation usually remain intact.
hope it helps you
Answer:
A fuse wire is made up of an alloy with a low melting point. The heat produced due to short circuit melts the fuse
wire and breaks the circuit.
